由于油井所处区域的地理位置、开发前期工艺水平、工程设计水平、生产井管理水平、各种增产措施及油层改造措施等因素,都有可能造成生产井不能正常工作,经常会发生各种形式的卡钻事故。因此,迅速处理卡钻事故,是保障油井正常生产的重要措施。国内外相关文章的检索及相关技术的调研表明:测卡与爆炸松扣解卡比常规解卡方法更具有作业时间短、费用低、成功率高等优点。 Due to the geographical location of the well, the pre-development stage, the engineering design level, the well management level, various stimulation measures and the oil recovery measures and other factors, are likely to cause the production wells can not work properly, often occur in various forms Card stuck accident. Therefore, the prompt handling of stuck pipe accidents is an important measure to ensure the normal production of oil wells. Research on the retrieval of related articles at home and abroad and the related technologies show that the card testing and the explosion loose card solution have the advantages of shorter working time, lower cost and higher success rate than the conventional card de-carding method.
